What is the difference between oxygen special ball valve and ordinary ball valve?

Oxygen ball valve is a special ball valve specially designed for oxygen pipe network, which has its own characteristics besides the functions of ordinary ball valves. Take the oxygen ball valve of VTON in Wighton, USA as an example, strict oil prohibition measures are adopted in the manufacture, and all parts have undergone strict degreasing treatment before installation. All sizes of ball valves have conductive screw holes at the flange end to prevent static electricity. The exposed part of the ball valve has protective measures to prevent dust and oil pollution.

Summarize the difference between oxygen special ball valve and ordinary ball valve.

The sealing grade of oxygen ball valve is very high, and both soft seal and metal seal are required to reach ANSI B16.104 Class V; There is also a kind of metal sealed oxygen ball valve internals and valve seat to be hardened; Fire safety ball valve should also have anti-static structure; Bidirectional sealing; All oxygen ball valves must be degreased, and copper is prohibited. If there are oxygen ball valves with electrical equipment, such as imported oxygen solenoid valves, imported oxygen electric regulating valves, imported oxygen electric ball valves and imported oxygen electric butterfly valves from Witton, USA, the protection level of field instruments should at least reach IP65, and the explosion-proof level should at least reach EExdIICT4/.
